Technology Process of Niobium(II) oxide

There total 2 articles about Niobium(II) oxide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

oxygen (80937-33-3) + niobium pentachloride (10026-12-7) → niobium oxide (12034-57-0)

Guidance literature:

NbO is prepared in a 2450-MHz electrodeless discharge through a flowing mixt. of NbCl5 vapor, O2, and helium.; Monitored by eye with spectroscope, not isolated.;

DOI:10.1016/0022-2852(88)90111-7

Reference yield:

niobium + water (7732-18-5) → niobium(II) oxide + NbH(OH) + Nb(OH2) (12034-57-0) + H2NbO (324530-72-5)

Guidance literature:

In solid matrix; the laser-ablated metal atoms were co-deposited with H2O in excess argononto an 11 K CsI window; not sepd., detected by IR spectra;
